MAIN POINTS TO KNOW FROM THE HANDOUTS:

Arrays

-- Key terms: zero-based; length attribute; index (subscript); aliasing problem

-- Know the various ways to declare an array (1. without allocating memory for it.
2. Allocating memory for a certain size array. 3. Using an array literal.)

-- Know that an array is accessed via a handle

-- Differences in what's stored between an array of primitive-type values and an array of reference-type values

-- How to declare an array parameter; how to construct an array to be returned from a method.

-- How to declare a two-dimensional array; how it is stored (rowwise); how to access a row; an element

-- Be able to read/write code using loops to process arrays (like the ones on Slide #9 in average() and in printStats() and those in Lab 9.)

-- Nothing on command-line arguments

Files

-- Key terms: stream;

-- Know how to do output with System.out

-- What's a basic difference between Streams and Readers/Writers? (char vs. byte I/O)

-- How do BufferedReaders and BufferedWriters improve program performance?

-- With readLine(), how can we tell when the end of the file has been reached?

-- What should be done when a reader/writer is finished? (close it. How?)

-- Know how try-catch mechanism works and how to use it.
